Mattea was asked to find the measure of an interior angle of a regular octagon.
Mattea’s work is shown below.
Steps
Mattea’s Work
Step 1
(n minus 2) 180 degrees = (9 minus 2) 180 degrees
Step 2
7 (180 degrees) = 1260 degrees
Step 3
1260 degrees divided by 8 = 157.5 degrees
Where, if at all, did Mattea first make a mistake finding the measure of an interior angle?
step 1
step 2
step 3
Mattea did not make a mistake.
